Port Repels and the other non-fishing field items

Repel, Super Repel and Max Repel count down 100, 200 or 250 steps where
CountStep does, keep weaker wild Pokémon away from the first party member
that has not fainted, and print "REPEL's effect wore off." on the last
step. The Coin Case and the Blue Card show their balances, Sacred Ash
revives the party once one Pokémon has fainted, and the Normal and
Gorgeous Boxes send their trophy home.

The Itemfinder looks for unfound hidden items on the original's screen
around the player. The Card Key, the Basement Key and the Squirtbottle
run the original's checks for their doors and Sudowoodo, whose maps are
not open yet. Saves gain the Repel's steps, the coins and the Blue Card's
points.
